I installed this extension in order to use "Fix Common Shove" by jensewe. At first everything seemed fine, but then I woke up the next day to the server crashing as soon as anyone joins and over 40+ of this same crash report on the dashboard: https://crash.limetech.org/tz7hcbgc7xra
Disabling the aforementioned plugin was not sufficient, I had to unload this extension in order for anyone to join again.
Sorry for this inconvenience. There was a regression that caused linux build to crash server. Should be fixed now.
